Power Limiters
Keysight's power limiters provide the best broadband input protection from excess RF power, DC transients and ESD, for a variety of RF and microwave instruments and components. For example, the input circuitry of spectrum analyzers, network analyzers, frequency counters or amplifiers can be protected from unintentional inputs up to 5 watts average power. At even greater power levels, failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.

Multi-Spectral UV/Laser Range Stimulator
Phantom™
The Phantom is a long-range laser and ultraviolet (UV) stimulator capable of testing aircraft electro-optical sensor suites up to 5 km. Phantom can operate as an independent laser and/or UV stimulator or can be integrated with our other electro-optical and radio frequency range systems (see GTESS and PRTS). The Phantom provides both a laser threat and a synchronized temporal missile plume signature to stimulate both the aircraft’s laser and missile warning systems. Training aircrew to counter maneuver a Laser Beam Riders (LBR) threat is considered essential to survival and in-air training. The Phantom can be deployed either on a shoulder or tripod mount.

Computer-Based Instruments
GT210PCIe
with the GT210PCIe you can determine any frequency to 0.01 part per million (eight digits) in just 1 mS, and resolve each time measurement to 8pS. Couple that with 2300 measurements per second, one of the fastest rates available and you can acquire more data in a single second than a typical GPIB counter can in one minute! Faster measurements and higher resolution, along with built-in statistics functions give you a more thorough analysis of your signal. Standard deviation, peak to peak jitter, or a graph of the measurements are available at the push of a button.

Resonance Dip Meter
NRM-2
National RF’s Resonance Dip Meter is a test instrument used to determine the resonant frequency of a tuned circuit or resonant network, such as an antenna system. In addition, the unit may function as an RF detector, or a secondary frequency source. The instrument is analogous to the older vacuum tube “grid dip meter,” once popular in every electronic laboratory or radio station. Unique to this updated version is a buffered output that may drive a digital frequency counter for exact measurement of resonant frequency, or connected to an oscilloscope to be used as an RF detector and waveform/modulation monitor.

Large-Displacement Low-Frequence Vibration System
9363-LN-100
King Design Industrial Co., Ltd.
This tester is designed to assess the damage made to product packaging and internal objects caused from transporting environment; to discover the packaging flaw and product’s early failure from a long-term cumulative vibration fatigue; avoid man-made transporting damage and improve product’s reliability and quality of delivered products. With the use of high-performance foot absorber, the resonance effect to floor caused by the bounce test may be waived; and can reduce the pile’s destruction to industrial plants. Two displays can make comparative display on both frequency and rpm at the same time; thus no need to switch in order to read these two values. The dual-control mode of time accumulator and counter can avoid human error resulting from the conversion. Easy to operate; no need for complicate training program.
